Which value of the variable m satisfies the equation 20 = -2(4m - 5)

m = - 1.25

Step-by-step explanation:

20 = - 2(4m - 5) ← divide both sides by - 2

- 10 = 4m - 5 ( add 5 to both sides )

- 5 = 4m ( divide both sides by 4 )

- = m , that is

m = - 1.25

which value of the variable m satisfies the equation 20 = -2(4m - 5)

20 = -2(4m - 5)

20 = -8m + 10

20 = -8m + 10

20 - 10 = -8m + 10 - 10

20 - 10 = -8m + 10 - 10

10 = -8m + 10 - 10

10 = -8m + 10 - 10

10 = -8m

10 = -8m

(Cancel -8, In the numerator and the denominator)

m = -1.25

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
